Standard Ignition TS-383 Engine Coolant Temperature Sender

Engine Coolant Temperature Sender for Gauge Applications

Standard Ignition TS-383 is an engine coolant temperature sender built for gauge-equipped Dodge trucks and Ramcharger applications. It uses a bolt-on mounting style, a round female plug-in connector, and a 2-blade male terminal layout for direct replacement service.

Key Features

• Engine coolant temperature sender for gauge systems
• Bolt-on attachment method for secure installation
• Round female connector with plug-in design
• 2 male blade terminals for electrical connection
• Factory-calibrated and tested for specified actuation temperature
• Built with a formed bimetallic contact arm for precise switching action
• Standard Ignition TS-383 replacement part number

Product Details

Standard Ignition TS-383 is engineered for vehicles that rely on a coolant temperature signal for the dash gauge. The sender uses thermal-switch construction with calibrated actuation points, and the internal bimetal design responds to temperature changes through controlled metal expansion. Standard Ignition manufactures and tests each unit to confirm switch operation at the specified temperature, helping maintain consistent gauge input in service applications. This part cross-references Four Seasons 37975 for the same application.

Installation Notes

Confirm connector style, terminal count, and gauge-equipped application before installation. Match the bolt-on mounting point and verify the sender is specified for the vehicle’s temperature gauge circuit. Clean the mounting surface and inspect the harness connector for corrosion or looseness before connecting the new unit.

Quality Assurance

Standard Ignition uses controlled manufacturing, calibration, and testing procedures to verify switch actuation at the specified temperature. The TS-383 is produced under complete quality control from component selection through final inspection.
